  Linux Candy is a series of articles covering interesting eye candy software. We only feature open source software in this series.

  Some of the programs in this series are purely cosmetic, frivolous pieces of fun. Candy at their finest. But we also include some programs that aren’t purely decorative.

  There’s a diverse range of programs included in this series. Programs such as eDEX-UI and Variety are actually highly practical programs. ASCIIQuarium has soothing and relaxing qualities for your desktop. Other programs included in this series (such as lolcat, cacafire) are included purely for their decorative qualities.
